ADAPTER.

Specification of Letters Patent.

Application led October 16, 1911. Serial No. 655,056.

the invention is to provide this connection which will prove exceedinglyuseful and desirable in houses, oi'lioes, public buildings, and thelike, when it is desired to convert the ordinary flush plug receptacleinto a connection whereby the current may be conveyed to a lamp, motor,vacuum cleaner, flat-iron, percolator, or other electrical apparatus.

A further object of the vinvention isto rovide a device of the characterstated -which will be capable of instantaneous application and removalwith reference to any type of receptacle, and to which the usualroundscrevvr attachment plug may be readily attached'for connection witha lamp fixture or the like.

'Other objects of the invention are the provision of an adapter whichwill obviate the use of two or more different types of attachas it isnow required; which can be made to accommodate one, two or threesockets, thus enabling one socket to be used fora connection with anincandescent lamp, another to be connected to the conducting wires of amotor, and so forth, as will be readily understood. I may in thisconnection however, substitute for the sockets, binding posts or otherelectrical connecting devices, so that instead of screwing incandescentlamps or attachment plugs into the sockets, it will be possible toconnect wires to the binding posts direct, or I may use both socket andbinding post, as the occasion re uires.

invention further consists of an adapter embodying novel features ofconstruction and combination of arts for service substantially,asdisclosed crein.

In the accompanying drawings, I have illustrated a practical physicalembodiment of the best mode I have so far devised for accomplishing theobjects heretofore stated, it .being understood that such changes,alterations and modifications may be made as fall clearly within thescope of my invention without departing in any way from the spiritthereof or sacrificingany of its advantages.

Figure 1 is a side elevation of the adapter,

flush plug receptacle and incandescent lamp, showing the adapter inapplied position. Fig. 2 is a longitudinal sectional view of theadapter. Fig. 3 is an end view of, the adapter as seen from the left inFig. 2. Fig. 4 is an end view of the adapter as seen from the right inFig. 2. Figs. 5 and .6 are perspective views of the adapter with two andthree sockets, respectively, for use when a cluster of lights isdesired, binding posts being also shown for connection with conductingWires, as an alternative form of connection.

In the drawings the numeral 1 designa'tes the flush plug receptaclegenerally, having the contact points 2, secured to the inner wallsthereof, and the lead wires 3 connected to a suitable source of current.

The adapter proper comprises a block of wood or other insulatingmaterial 5, of sub- .stantially circular shape and is cut awaymtermediate its length to form the rectilinear-shaped portion 6. Theupper or top portion'of contact member or disk 7, which has a finger orstrip 8 extending downwardly alon the cut-away portion 6 of the block,ang the opposite slde of the block is provided with the block 5 isprovided with a the strip 9 having the spring-pressed clip or contact 10formed integral t terposed between said contacts 7 and 10 is the disk ofinsulation material 11, the purpose of which is obvious. 4

The contacts S and 9 are secured upon the upper portion of the block 5by any suitable means such 'as screws, or the like, while mounted uponthe block 5 is the ordinary threaded socket 12 for attachmentV to thecorresponding socket of an ordinary incandescent lamp. The current thustravels along contact 8 and is transferred to the screw shell 12 bymeans of the usual soldered connection 12", which solder also serves toretain the shell 12 upon the block 5.

The adapter is further provided with an outer casing or socket 13, ofordinary construction, said casing having the usual inerewith. In-

sulationilining 14 and being provided with the opposite openings 15, thespring clips 16 and the adjusting screws 17, the purpose of which isapparent.

It will be readily seen from the above description, taken in connectionwith the drawings, that when the adapter is inserted into the flush plugreceptacle and the contacts established, the current will follow thecontact ystrips 8 and 9. When the screw plug of an ordinary lamp andsocket is screwed upon the threaded socket l2, the contact membercarried by the lamp will bear upon the clip 0r contact 10 and thecircuit will thus be established.

In Figs. 5 and 6, respectively, sockets 1S are shown as enterin theadapter at substantially rightv ang es thereto, and the adapter isprovided with the binding posts or other electrical connections 19, towhich conducting wires may be fastened, and this form of adapter isparticularly useful when a cluster of lights from a single' receptacleis desired, it being understood that l do not limit myself to theprecise details of construction herein speciied. ltwill be alsounderstood `that there are a great many types of flush. plug receptaclesin common use, in which the adapter must be fitted,

vand that for this reason I do not Wish to confine myself to the preciseform of block and spring contact ingers shown, but reserve the right tochange the shape of the fingers and block to conform with the dit'-ferenttypes of receptacles, provided that I do not depart from the.essence and spirit of 4 the lnvention, which is to provide means forconverting an ordinary flush plug receptacle with said lamp mariees Hushplug receptacle having Contact points,`

of an adapter comprising a block, spring contact plates attachedthereto, conductor disks formed integral withsaid plates, an insulation'disk interposed between said disks, and a threaded socket for attachment2. A device of the character described,

,comprising a block having a rectilinear cutaway portion, spring contactplates attached thereto, conductor disks formed integral with saidplates and secured upon the top of said block, an insulation diskinterposed between said conductor disks, a threaded socket, an outercasing, an insulating matelrial therebetween, and means for securingIsaid casing upon said block.

3. The combination with a Hush plug re- .ceptacle, having Contactpoints, of an ,adapter fitting in said receptacle'and contacting withsaid points, said adapter com-v prising a block, spring Contact platesattaehed thereto, conductor disks formed integral with said plates, aninsulation disk 'interposed between said disks, and means for conveyingthe current from said conductor disks to a plurality of electricalconnections.

in testimony whereof I affix my signature in presence of two witnesses.
